Description

Technical Field

[0001] The utility model relates to the technical field of cable installation equipment, in particular to a ladder-type cable bridge. Background Art

[0002] Cable tray refers to a rigid structural system that is composed of trough-type, tray-type or ladder-type straight sections, elbows, tees, cross-way components, as well as support arms (arm-type brackets), hangers, etc., which can closely support cables.

[0003] Cable trays are divided into trough type, tray type, ladder type, grid type and other structures, and are composed of brackets, brackets and installation accessories. The cable trays in buildings can be erected independently or attached to various buildings (structures) and pipe gallery brackets. They should have the characteristics of simple structure, beautiful shape, flexible configuration and convenient maintenance. All parts must be galvanized. For cable trays installed outside buildings in the open air, if they are near the sea or in a corrosion zone, the material must have the physical properties of corrosion resistance, moisture resistance, good adhesion and high impact resistance.

[0004] The ladder-type cable tray has the characteristics of high strength, light weight, low cost, beautiful appearance, easy installation and good air permeability. It is suitable for the laying of cables with larger diameters, and is particularly suitable for the laying of high and low voltage cables with large loads. However, the traditional ladder-type cable tray consists of two U-shaped side panels and multiple ladder steps fixed between the two U-shaped side panels. The two ends of the ladder steps are welded and fixed to the U-shaped side panels, and the width cannot be adjusted, which cannot meet the laying requirements of cables of different sizes.

[0005] Therefore, it is necessary to provide a ladder-type cable tray to solve the above-mentioned technical problems. Utility Model Content

[0007] The above-mentioned technical objective of the utility model is achieved through the following technical solutions: a ladder-type cable tray comprises a U-shaped side plate, wherein the U-shaped side plates are provided with two, and the relative inner sides of the two U-shaped side plates are fixedly installed with a first ladder step, the first ladder step is provided with multiple groups, and the relative inner sides of two first ladder steps in the same group are slidably connected with a second ladder step together, multiple first ladder steps are provided with multiple grooves, multiple bottom walls of the grooves are fixedly installed with springs, and tops of multiple springs are fixedly installed with limiting columns, multiple second lifting gears are provided with first sliding grooves at both ends of the top sides, multiple first sliding grooves are provided with multiple main locking grooves on the bottom walls, multiple limiting columns can penetrate the corresponding main locking grooves, baffles are slidably installed in the two first sliding grooves, and multiple slave locking grooves are provided on the two baffles, multiple limiting columns are adapted to the corresponding slave locking grooves, and the number of multiple main locking grooves is twice the number of multiple slave locking grooves.

[0008] By adopting the above technical solution, under normal circumstances, multiple limit columns first pass through the grooves to pass through the corresponding main locking grooves, and then pass through the corresponding slave locking grooves. Finally, the top ends of the multiple limit columns are located above the baffle, and the first ladder step is locked with the second ladder step through the limit column and the main locking groove. When the position of the two U-shaped side panels needs to be adjusted, the baffle is first pushed in the direction of the U-shaped side panel. When the baffle slides, the multiple limit columns are squeezed downward, and the multiple springs are compressed. When the multiple limit columns are squeezed by the baffle to the bottom of the multiple main locking grooves, the U-shaped side panel is pulled outward, and the U-shaped side panel drives the multiple limit columns through the multiple first ladder steps. Move outward, after the U-shaped side plate and multiple first steps are moved to the appropriate position, the positions of the multiple baffles can be readjusted, and the corresponding multiple limit columns can be reset by multiple springs. The multiple limit columns can pass through the grooves from the main locking groove to the slave locking groove again, and the first step and the second step with adjusted widths can be locked to prevent the first step and the second step from shaking and offsetting each other. The first step and the U-shaped side plate can be moved outward through the limit columns, springs, main locking grooves and slave locking grooves, so that the widths of the first step and the second step can be adjusted to meet the laying requirements of cables of different sizes.

[0009] The utility model is further configured as follows: first limiting grooves are provided on opposite inner sides of the plurality of grooves, first limiting rods are fixedly installed on both sides of the plurality of baffles, and the plurality of first limiting rods are matched with the corresponding first limiting grooves.

[0010] By adopting the above technical solution, a plurality of baffles are slidably connected to the second gear lifting device through the first limiting groove and the first limiting rod, and the first limiting groove and the first limiting rod prevent the baffles from being offset when moving.

[0011] The utility model is further configured as follows: a second slide groove is provided on both sides of a plurality of the second gear shifting means, and a plurality of the main locking grooves are connected to the corresponding second slide grooves.

[0012] By adopting the above technical solution, a plurality of second lifting gears are slidably connected to the corresponding first ladder gears through the corresponding second sliding grooves, and a plurality of limiting columns pass through the top wall of the second sliding groove through the main locking groove.

[0013] The utility model is further configured as follows: second limiting grooves are provided on the relative inner sides of the plurality of second sliding grooves, second limiting rods are fixedly installed on both sides of the plurality of first ladder steps, and the plurality of second limiting rods are adapted to the corresponding second limiting grooves.

[0014] By adopting the above technical solution, during use, when the cable is laid on multiple first steps and second steps, multiple second limiting grooves and multiple second limiting rods make the first steps more stable in the second slide groove, preventing the first steps from shifting up and down when supporting the cable in the second slide groove.

[0015] The utility model is further configured as follows: handles are fixedly mounted on the top sides of the plurality of baffles, and the handles are provided in plurality.

[0016] By adopting the above technical solution, it is more convenient for an operator to push the baffle through the handle.

[0017] The utility model is further configured as follows: a plurality of the springs are each provided with a support column, the bottom ends of the plurality of the support columns are each fixedly connected to the corresponding bottom wall of the groove, a plurality of the limit columns are each provided with a support groove (not shown in the figure) on the bottom side, the top ends of the plurality of the support columns are each placed in the corresponding support groove, and the plurality of the support columns are each slidably connected to the corresponding limit columns via the support groove.

[0018] By adopting the above technical solution, when the limit column moves up and down, the support column also slides up and down in the support groove, preventing the spring at the bottom end of the limit column from deforming when moving up and down, thereby affecting the resetting of the limit column.

[0019] To sum up, the utility model has the following beneficial effects: the utility model presses the limit column with a spring fixed at the bottom end to the bottom of multiple main locking grooves through the baffle, and then pulls the U-shaped side plate outward, and the U-shaped side plate drives multiple limit columns to move outward through multiple first ladder steps. After moving to a suitable position, the position of the baffle is readjusted, and the multiple limit columns can pass through the groove from the main locking groove to the slave locking groove again to lock the first ladder step and the second ladder step, so that the width of the first ladder step and the second ladder step can be adjusted to meet the laying requirements of cables of different sizes.
